What pulls against what
- fast retries vs. single execution
- legacy compatibility vs. stronger guarantees
- customer certainty vs. uncertain networks
What is at stake
A small retry defect can become an overpayment and reconciliation problem for customers. A dependable fix restores confidence at the moment money leaves an account
Why Mercury
For Mercury, it often matters because operating payments need to remain dependable under ordinary connectivity failures.
